You are right, if you don't play carefully you can never save your deposit and if you leave it on the casino site you will fall into the trap of fraud later. When you gamble with your real money the most important thing is that you can be sure and secure that your transaction is safe and that you get your winnings without any delay and quickly. Good online casinos care about these things and strive to provide the highest and best service possible. gambling sites should be analyzed to choose the right casino.
No matter how good or trusted the site is, the end responsibility remains on the user to keep his funds save and not to over trade. Being a responsible gambler is more in favor of the gambler and not for the gambling casino because they wants that people wager more and therefore more chances of losing the money.
From my own view, it is better for me not to engage the use of any gambling platform than when am not having the best reliability i should have achieved being secured in them, i see no reason why i should be afraid of leaving my money on the casino wallet even when am not gambling, at least it is commonly believed that any money sent to the casino should be assumed being intended for the purpose of gambling, so why should i be afraid of anything, but most gamblers finds it very difficult in believing in some of these gambling casinos and yet they are using them.
